returns the dot product between row i1 and row i2 (considering only the inputsize first elements). The default version in VMatrix is somewhat inefficient, as it repeatedly calls get(i,j) The default version in RowBufferedVMatrix is a little better as it buffers the 2 Vecs between calls in case one of them is needed again. But the real strength of this method is for specialised and efficient versions in subbclasses. This method is typically used by SmartKernels so that they can compute kernel values between input samples efficiently.

Mat PLearn::ForwardVMatrix::toMat | ( | ) | const [virtual] |
returns a Mat with the same data as this VMat The default version of this method copies the data in a fresh Mat created in memory However this method will typically be overrided by subclasses (such as MemoryVMatrix) whose internal representation is already a Mat in order to return this Mat directly to avoid a new memory allocation and copy of elements. In this case, and in this case only, modifying the elements of the returned Mat will logically result in modified elements in the original VMatrix view of it.
